Summary
SRPK1 (SRSF protein kinase 1, HGNC:11305) is a protein-coding gene on chromosome 6p21.31, encoding SRSF protein kinase 1 (Q96SB4). Serine/arginine-rich protein-specific kinase which specifically phosphorylates its substrates at serine residues located in regions rich in arginine/serine dipeptides, known as RS domains and is involved in the phosphorylation of SR splicing factors and the regulation of splicin….
This gene encodes a serine/arginine protein kinase specific for the SR (serine/arginine-rich domain) family of splicing factors. The protein localizes to the nucleus and the cytoplasm. It is thought to play a role in regulation of both constitutive and alternative splicing by regulating intracellular localization of splicing factors. Alternative splicing of this gene results in multiple transcript variants. Additional alternatively spliced transcript variants have been described for this gene, but their full length nature have not been determined.

Function. Serine/arginine-rich protein-specific kinase which specifically phosphorylates its substrates at serine residues located in regions rich in arginine/serine dipeptides, known as RS domains and is involved in the phosphorylation of SR splicing factors and the regulation of splicing. Plays a central role in the regulatory network for splicing, controlling the intranuclear distribution of splicing factors in interphase cells and the reorganization of nuclear speckles during mitosis. Can influence additional steps of mRNA maturation, as well as other cellular activities, such as chromatin reorganization in somatic and sperm cells and cell cycle progression. Isoform 2 phosphorylates SFRS2, ZRSR2, LBR and PRM1. Isoform 2 phosphorylates SRSF1 using a directional (C-terminal to N-terminal) and a dual-track mechanism incorporating both processive phosphorylation (in which the kinase stays attached to the substrate after each round of phosphorylation) and distributive phosphorylation steps (in which the kinase and substrate dissociate after each phosphorylation event). The RS domain of SRSF1 binds first to a docking groove in the large lobe of the kinase domain of SRPK1. This induces certain structural changes in SRPK1 and/or RRM2 domain of SRSF1, allowing RRM2 to bind the kinase and initiate phosphorylation. The cycles continue for several phosphorylation steps in a processive manner (steps 1-8) until the last few phosphorylation steps (approximately steps 9-12). During that time, a mechanical stress induces the unfolding of the beta-4 motif in RRM2, which then docks at the docking groove of SRPK1. This also signals RRM2 to begin to dissociate, which facilitates SRSF1 dissociation after phosphorylation is completed. Isoform 2 can mediate hepatitis B virus (HBV) core protein phosphorylation. It plays a negative role in the regulation of HBV replication through a mechanism not involving the phosphorylation of the core protein but by reducing the packaging efficiency of the pregenomic RNA (pgRNA) without affecting the formation of the viral core particles. Isoform 1 and isoform 2 can induce splicing of exon 10 in MAPT/TAU. The ratio of isoform 1/isoform 2 plays a decisive role in determining cell fate in K-562 leukemic cell line: isoform 2 favors proliferation where as isoform 1 favors differentiation. Phosphorylates the N-terminus of ERC1.
Subunit / interactions. Monomer. Isoform 2 is found in a multisubunit complex containing seven proteins, named toposome, which separates entangled circular chromatin DNA during chromosome segregation. Isoform 2 interacts with DNAJC8 and AHSA1/AHA1 and this mediates formation of a complex with the Hsp70 /Hsp90 machinery. Isoform 1 is found in a complex with: DHX9, MOV10, MATR3, HNRNPU, NCL, DDX21, HSD17B4, PABPC1, HNRNPM, IGF2BP1, SYNCRIP, RPL3, VIM, YBX1, NPM1, HNRNPA2B1, HNRNPC, RPLP0, RPL7A and RALY. Isoform 2 binds to IGF2BP1, SYNCRIP, HNRNPA2B1 and HNRNPC. Isoform 1 and isoform 2 interact with SAFB which inhibits its activity. Isoform 2 interacts with SAFB2 which inhibits its activity. Interacts (via kinase domain) with ERC1 (via N-terminus); the interaction is direct and may be involved in SRPK protein localization. (Microbial infection) Isoform 2 interacts with HHV-1 ICP27 protein.
Subcellular location. Cytoplasm. Nucleus. Nucleus matrix. Microsome Cytoplasm. Nucleoplasm. Nucleus speckle. Chromosome.
Tissue specificity. Isoform 2 is predominantly expressed in the testis but is also present at lower levels in heart, ovary, small intestine, liver, kidney, pancreas and skeletal muscle. Isoform 1 is only seen in the testis, at lower levels than isoform 2. Highly expressed in different erythroid and lymphoid cell lines, with isoform 2 being far more abundant than isoform 1.
Activity regulation. Activated by phosphorylation on Ser-51 and Ser-555.
Miscellaneous. Due to intron retention.
Similarity. Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family.

Reactome pathways and GO biological processes over-represented among this gene’s 218 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
